The European Commission has announced the adoption of its Energy Roadmap 2050, which explores the challenges of decarbonising the European Union while ensuring security of energy supply and economic competitiveness.

The roadmap’s analysis concludes that decarbonisation of the energy system is "technically and economically feasible" and that energy efficiency and renewables are a critical part of the mix. Its analysis is based on scenarios created by combining, in different ways, the four main decarbonisation routes – namely, energy efficiency, renewables, nuclear, and carbon capture and storage (CCS).
